Superconducting Circuit Structure, Superconducting Quantum Chip And Superconducting Quantum Computer

A superconducting circuit structure, a superconducting quantum chip, and a superconducting quantum computer are provided, which relate to the field of quantum computing. The superconducting circuit structure includes: at least two qubits; a connector, coupled with the two qubits respectively, to realize transversal coupling with each of the two qubits; and a coupler, coupled with the two qubits respectively, to realize longitudinal coupling with each of the two qubits. Therefore, the .sigma..sub.z.sigma..sub.z parasitic coupling between the qubits is effectively removed, and a two-qubit gate with high fidelity is obtained.
